This child uses the visual arrangement of a ten frame to conceptually subitize quantities into the teen numbers. He recognizes a full row as a unit of 5 and uses that to derive larger numbers as five-and-some-more. The adult is gently nudging him to unitize the full frame as a ten.

Focus on the Child videos are taken from one-on-one interviews with individual children. The interviews are designed to elicit evidence of children’s mathematical thinking. They are not teaching episodes or formal assessments.
